1991 10v engine info needed

[MHLIGGINS <MHLIGGINS@aol.com>]

     As I've mentioned, I bought a 1991 10v engine to put in my '87 quat.  I
know there are some differences between it and what I took out.  I know it
uses a K-24 turbo, I bought that as well.
     What is the compression ratio?
     What are the factory specified spark plugs?  (It had Bosch tri-electrodes
in it)
     Is the horsepower the same as the '87?
     Anything else I should know (but can't remember to ask)?

     Thanks.
